Merge git://www.linux-watchdog.org/linux-watchdog 

Pull watchdog updates from Wim Van Sebroeck:
 - Removal of the Documentation/watchdog/00-INDEX file
 - Fix boot status reporting for imx2_wdt
 - clean-up sp805_wdt, pnx4008_wdt and mpcore_wdt
 - convert printk in watchdog drivers to pr_ functions
 - change nowayout module parameter to bool for every watchdog device
 - conversion of jz4740_wdt, pnx4008_wdt, max63xx_wdt, softdog,
   ep93xx_wdt, coh901327 and txx9wdt to new watchdog API
 - Add support for the WDIOC_GETTIMELEFT ioctl call to the new watchdog
   API
 - Change the new watchdog API so that the driver updates the timeout
   value
 - two fixes for the xen_wdt driver

Fix up conflicts in ep93xx driver due to the same patches being merged
through separate branches.

* git://www.linux-watchdog.org/linux-watchdog: (33 commits)
  watchdog: txx9wdt: fix timeout
  watchdog: Convert txx9wdt driver to watchdog framework
  watchdog: coh901327_wdt.c: fix timeout
  watchdog: coh901327: convert to use watchdog core
  watchdog: Add support for WDIOC_GETTIMELEFT IOCTL in watchdog core
  watchdog: ep93xx_wdt: timeout is an unsigned int value.
  watchdog: ep93xx_wdt: Fix timeout after conversion to watchdog core
  watchdog: Convert ep93xx driver to watchdog core
  watchdog: sp805: Use devm routines
  watchdog: sp805: replace readl/writel with lighter _relaxed variants
  watchdog: sp805: Fix documentation style comment
  watchdog: mpcore_wdt: Allow platform_get_irq() to fail
  watchdog: mpcore_wdt: Use devm routines
  watchdog: mpcore_wdt: Rename dev to pdev for pointing to struct platform_device
  watchdog: xen: don't clear is_active when xen_wdt_stop() failed
  watchdog: xen: don't unconditionally enable the watchdog during resume
  watchdog: fix compiler error for missing parenthesis
  watchdog: ep93xx_wdt.c: fix platform probe
  watchdog: ep93xx: Convert the watchdog driver into a platform device.
  watchdog: fix set_timeout operations

Other IOCTLs can be served using the ioctl-callback. Note that this is mainly

timer device. It returns 0 on success, -EINVAL for "parameter out of range"

value of the watchdog_device will be changed to the value that was just used
to re-program the watchdog timer device.

routine should set the timeout value of the watchdog_device to the
achieved timeout value (which may be different from the requested one
because the watchdog does not necessarily has a 1 second resolution).

watchdog's info structure).
